VAAI

OneFS uses VMware vSphere API for Array Integration (VAAI) to support offloading specific virtual machine storage and management operations from VMware ESXi hypervisors to an Isilon cluster.

VAAI support enables you to accelerate the process of creating virtual machines and virtual disks. For OneFS to interact with your vSphere environment through VAAI, your VMware environment must include ESXi 5.0 or later hypervisors.

If you enable VAAI capabilities for an Isilon cluster, when you clone a virtual machine residing on the cluster through VMware, OneFS clones the files related to that virtual machine.

To enable OneFS to use VMware vSphere API for Array Integration (VAAI), you must install the VAAI NAS plug-in for Isilon on the ESXi server. For more information on the VAAI NAS plug-in for Isilon, see the VAAI NAS plug-in for Isilon Release Notes.
